The potential of natural and artificial wetlands for phosphorous removal in the Harvey catchment

Summary:

An assessment was made of the potential for using various management options, involving wetland filters, to reduce phosphorus loadings into Harvey Estuary, The study involved a literature survey, study of existing wetlands in the Harvey catchment, and examination of phosphorus uptake by experimental wetlands. Up to 90% reduction in phosphorus concentration was achieved at high input concentration and low flow rates, However, the use of artificial wetlands along the borders or outlets of drains was not considered feasible, as high rates of water movement into the drainage system would preclude efficient phosphorus retention by the filter. The use of artificial wetlands at the outlet of certain point sources, e,g, piggeries, is likely to be effective, although further work on design and efficiency of the wetland filter would be required before implementation.

Diversion of agricultural runoff into existing natural wetlands was not recommended as the majority of wetlands in the catchment have higher phosphorus concentrations than the runoff, due to removal of fringing vegetation from swamps in farmland. Overflow from these swamps into drainage canals may provide a significant source of phosphorus to the estuary, although the actual quantity, on a catchment basis, is not known. There appears to be no practicable way of reducing the amount of phosphorus contributed in this overflowing water, which would be effective in the short term. In the long term, reintroduction of fringing vegetation (including sedges and trees) sited around wetlands and at areas of overflow, may be profitable.

Bauxite mining in the Jarrah Forest: Impact and rehabilitation

Summary:

Research programmes and investigations being carried out by staff of State Government Departments, Alcoa of Australia, CSIRO and Tertiary Institutions are continuing to improve our understanding ofthe impact of bauxite mining on the water resources and environment of the Darling Range. They are also guiding the development of improved rehabilitation and environmental management practices.

Although there is still much to be learned, there is now a good appreciation of the hydrology and forest ecosystem of the high rainfall region where mining is currently taking place. In addition, useful knowledge of the lower rainfall portion of the bauxite lease areas has been obtained from the general water resources assessment programme and from forest management and agricultural land use research studies.

In preparing this review, emphasis has been placed on the presentation of current knowledge together with an outline of research in progress and further work planned. This review is very timely. It marks the end of the first decade of research into the impacts of bauxite mining in the western zone of the forest, and sets the scene for a new period of co-ordinated research when the more difficult problems of mining in the eastern forest zone must be addressed.

Fish and benthic faunal surveys of the Leschenault and Peel-Harvey estuarine systems of south-western Australia in December 1974

Summary: The fish and benthic fauna of the Leschenault and Peel-Harvey estuarine systems were surveyed during December 1974. The estuaries contained a range of benthic fauna dominated by bivalve molluscs, polychaete worms and amphipods. Essentially the same groups of benthic species were present in both Leschenault and Peel-Harvey estuaries.

Environmental and health performance of waste to energy technologies

Summary:

Advice of the Environmental Protection Authority to the Minister for Environment under Section 16(e) of the Environmental Protection Act 1986

On 16 November 2011, the Minister for Environment wrote to the Chairman of the Environmental Protection Authority (EPA) and the Chairman of the Waste Authority, requesting that the two Authorities investigate the environmental and health performance of waste to energy technologies internationally.

This request sought information on:

  • legislation for the establishment and operation of waste to energy facilities, focussed on emissions, in jurisdictions where these facilities currently exist;
  • current emissions from established and operating best practice facilities; and
  • current and historical level of compliance of these facilities.

The Minister requested that the information gathered be from full-scale, commercial plants that process municipal solid waste (MSW) and from a variety of technology types.

To assist with this investigation, WSP Environment and Energy Ltd were engaged to undertake a technical review of waste to energy plants around the world. These technical reports are attached. The reports provide detailed information to address the issues identified by the Minister for Environment. This advice from the EPA and Waste Authority draws on the technical advice to make recommendations that are relevant to the Western Australian situation.
